ABSTRACT:
This invention relates to collet-type splices and collet-type dead ends and methods for splicing together two electricity transmission cables or terminating one electricity transmission cable, the cables comprising a composite core surrounded by a conductor. The collet-type fittings use a collet inside a collet housing to hold the composite cores without penetrating or otherwise weakening the core itself. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet and the composite core. The collet seats within the collet housing thereby holding the composite core with frictional forces. The design of the collet enables the composite core to stretch longitudinally through the collet to strengthen the frictional hold.
